Treatment of Lumbar Disc Herniation by Unilateral Pedicle Screw Fixation and Intervertebral Fu-sion

Abstract：Objective To evaluate the effect of unilateral pedicle screw fixation and intervertebral fusion for lumbar disc herniation( LDH). Methods From January 2010 to January 2013,43 cases of patients with LDH were treated by unilateral pedicle screw fixation and intervertebral fusion,there were 26 males and 17 females,with age of 40 to 56 years old(average 48. 2 years old). The operation time,blood loss,hospital stay were recorded. At 2 weeks,3 months,1 year after operation,X-ray film,vAS score,JOA score were used to evaluate the clinical effect. Results 43 cases were followed up for 12~30 months, with an average of 15. 2 months. vAS score were(8. 4 ± 1. 3)points preoperative,and(1. 21 ± 0. 41),(1. 11 ± 0. 32)points, (1. 09 ± 0. 29)points at 2 weeks,3 months and 1 year after operation respectively. The difference were statistically significant comparedwith vAS score before operation( P <0 . 0 5 ). JOA score was( 1 6 . 1 9 ± 2 . 7 0 )points preoperative and( 2 2 . 7 4 ± 2. 19)points,(24. 30 ± 1. 49)points,(27. 74 ± 1. 22)points 2 weeks,3 months and 1 year after operation respectively. The difference were statistically significant compared with JOA score before operation(P<0. 05). The symptoms were significantly improved. Conclusion Treatment of LDH by unilateral pedicle screw fixation and intervertebral fusion is a good method for treating LDH with definite effect,which shortening the operation time and reducing trauma.
